2. Comploximetric titration of different metals

3. Types of EDTA titration -Direct titration : the solution containing the metal ion to be determined is buffered to be the desired pH and titrated directly with standard DETA.

4. Back titration: Use for the substance which are not water soluble or determined substance and titrant can be too slow. https://www.youtube.com/watch?v=J91n8RUkhKc

5. Determination of magnesium using eriochrome black T indicator 1- Dilute 10 ml of the magnesium ion solution to 50 ml with distilled water. 2- add 3 ml of the buffer solution (pH= 10) and EBT indicator 3- titrate with EDTA solution The color changes from red to blue

6. Determination of unknown Mg ⁺⁺ solution using EBT indicator M.V(Mg)= MV(EDTA) M of Mg =
